If you can I'd chat to my doctor about Adhd and trying something like concerta! I'm able to recognize many of the things you are mentionning here and had positive effects from methylphenidate.
ADHD isn't a condition which spontaneously appears mid-life following an obvious difficult event like losing one's job for an extended period.
The comment was clear that these symptoms appeared after the job loss. It's a match for the symptoms of a depressive episode (which can and does appear after a difficult life situation) but not ADHD.
Suggesting that the commenter seek out stimulant medication is not good advice.
Many (including myself) have been successfully living with symptoms without treatment, but seeked my eoctors advice after having similar symptoms after a similar situation, and the result was adhd medication which helped.
Suggesting that someone talks to their doctor about symptoms is reasonable advice.
Edit0: and I wouldn't go around diagnosing people with depressive episodes from a single comment, were I in your shoes. Let their practicians do diagnoses, you know?
He is unemployed which likely means he has no doctor or that high end health care if the sort you’re assuming is not something he has access to. Poor Americans can go to the ER, but talking to someone with knowledge and capacity to prescribe psychotropics is not how this works.
